Cancers are nurses environment in which they live.The majority of cancers, including cancer of the hermit, lives in the seas and rivers, but among the hermits have not only deep, but also terrestrial species.
sanitation cancers called because they are omnivorous.Juveniles live in tidal bands, where it is easier to find food.Among the algae, they gather all the carrion, including the remains of animals.They eat like real foodies: leisurely bite claw and eat a small piece of it.
One female can lay over the year up to fifteen thousand eggs.Testicles she attaches to her abdomen and cares about them constantly raking in the area of the abdomen fresh, oxygenated water flows.Ten days later the larvae emerge from the eggs, which have to go through four stages of growth.
The body of the young crabs covered with a dense shell.Growing up in it can not be, so periodically the young crabs shed their shell and an increase in the amount covered by the new shell again.The fourth molt cancer hermit loses some of its shell in the abdomen forever.His long abdomen covered with skin, turned in under the breast and takes the form of a similar shell.
as if ashamed of this shame (at the same time fear of falling prey to other cancers), cancer hermit looking for a comfortable, abandoned shellfish shells and sticks to it its soft abdomen, and head and claws of leaves outside, but only so long untildanger.In an emergency, it is all squeezed into the shell and covers the entrance to her right, covered with a thick carapace claw, the benefit that the structure of cancer hermit allows him to sit comfortably in the shells of any shape.
Other cancers continue to continue to molt and grow.They live compactly.But crabs hermits - they are the complete opposite.They are - single.But in the meantime society like other creatures.For example, a hermit deep in their shells are allowed to settle an amazing and very poisonous fish - anemones, barnacles so they seem shaggy.Cancer willingly runs in a shell with actin and feeds it the remnants of his food.Although venomous actinium is often the cause of death of a predator, is aimed at cancer, living in a shell.And then he eats it with cancer.Land single permit in their "house" to settle polychaete worm, creating a unique community, both giving and shelter, and protection from predators.The worm does not allow annoying insects in the shell, and cancer protects the worm from predators of amphibians.
digestive system of a hermit crab is very interesting.From the mouth through the pharynx and esophagus, its food enters the stomach of the first equipped with toothed chitin tёrkami.Peretёrtaya food comes in the second division, which is filtered and fed into the intestine, digestive gland goes where digested.Breathes cancer hermit gills associated with his limbs.The eyes have a very complex structure, since they consist of a plurality of individual optical lenses, assembled in one eye, so his vision mosaic.
